ROTARY FILE

摘要

A card file having a rotor with radiating arms, each of which has a card-carrying tray detachably connected thereto. The rotor is mounted in a housing for rotation about a horizontal axis so that each tray can be brought to a detent-defined viewing position at which the tray is disposed in a substantially horizontal attitude affording ready access to the file cards carried thereby. Inwardly facing ribs on the lower portion of the housing have their edges concentric to the axis of the rotor to be engagable by the outer extremities of the trays as they traverse the lower portion of their orbit upon rotation of the rotor, to thereby prevent detachment of the trays from the rotor arms. The various components of the rotor are held assembled with one another and with the housing entirely without reliance upon screws, bolts, rivets or the like. Upon removal of the card trays from the rotor, they can be connected in side-by-side relationship by interengaging dovetails to form a rigid desk unit which facilitates reference to the contents of all of the trays.
